(c1. 257-244)- This invention relates to air conditioners. of

the typ'e covered by my pending application Serial No. '732,411 iled June 26, 1934,-which has matured into Patent No. 2,044,832, June 23, 1936,

5 of which thepresent application is a continuation in part, and has for its object to provide an air conditioner adapted for maximum contribution tothe comfort of a room equipped'with the invention. `To this end, it embodies a unit for modifying the` temperature of, and illuminating, ,the space within the room, positioned above the space .to be conditioned, with its parts arranged substantially symmetrically around a vertical axis, whereby it maydeliver cooled air inall directions vradiating substantially horizontally from 'said axis, above the space to be conditioned. I

It is'aimed to take advantage' of' convective action between the cooled air and the uncooled air in a room, to the point of highest efficiency,

this being accomplished by the aforesaid" delivery of the cooled air currents in substantially horizontal radiating directions from a somewhat centralized locus, to form a blanket Iof vcool air which sinks downwardly, at a distance from said locus, pushing ahead ofit-the uncooled air which moves inwardly to a-region below the unit from which it ascends to the intake of the unit, the latterbeing located below the marginal outlet so there will be no crossing of air currents. Simultaneouslyl aim to achieve a lighting effect which .whether functioning according to direct or' indirect lighting principles, (either of which may be attained in the present invention) will embody a. most eicient and highly satisfactorydiffusion of light to the sameroom.

'I o this end, the invention contemplates the use of a casing or hood arrangement having the verticalaxis and symmetrical features above men- 40 tioned, whereby. it forms the -means both for directing the cooled air currents in horizontally radiating directions, (or with a slight upward deection to increase the distance of "carryI before settling downwardly to -displace the warmer airfbelow) and for similarly or other- ,wise directing light rays in' outwardly radiating the function of the'above described diffusion of cooled air currents, also serves admirably as a light reector, adapted to diffuse the light rays so as to secure the most' eiiicient illumination 65 to be achieved.y

of a room, particularly where indirect lighting is nwhich:

ing the invention.

That is, it is an object to arrange the lightiig IA mechanism so that it does not cut down the output of the cooling mechanism.

With these and other objects in view my invention consists in the combination 'and con struction and arrangement of lthe various parts l.

thereof, whereby the objects vcontemplated are attained, as more Afully setforth in the accompanying specications, pointed out in the claims,

and illustrated in the accompanying drawings,

Fig. 21s a similar view of another form of the invention.

Fig. 3 `is asimilar view of another form of th`e invention.

Fig. 4 Iis a vertical sectional view of another embodiment of the invention.

Fig. 5 is a view of a .pedestal type unit embody- Fig. 6 is a view of a wall hung unit the invention.

The invention provides a casing including upper and lower casing members I0 and tI' respectively forming between them an annular conical air passage terminating at one extremity in the bottom inlet I2 which is covered by ,a grille 24 and at its other extremity in the peripheral voutlet i3.

An annular drip eave Ilis supported on a tunco conical skirt I5, secured to the lower casing member Il, and is extended inwardly l.to form a shroud having an opening I6 registering with the intake of the fanvF.

` Below theeave I4 isa condensate trough I1, 4 which .receives condensate collected by the eave Il 'and escaping through the holes I8 therein. A lter I9 is positioned just below the trough embodying u I1, substantially traversing the spanJ thereof.

the space between the eave I4 and the upper 59` *casing member I0. I

The outer regions of the members I Il'and Ill are inclined upwardly soas to dei-lect upwardly the air delivered -by the fan F and the member Il is generally in the formI of a downwardly dished bowl.

-The lighting rmeans in this case comprises a series of .electric lamps.26 arranged around the periphry.of the skirt I5 and supported thereon.

',These lamps are positioned below the path of the conditioned air issuing from the conditioner so as to minimize their heating eilect, which detracts from the cooling effect of the element 25, here illustrated as a finned cooling coil.

The casing members Il and I0 cooperate to reflect the light upwardly and outwardly, whereby a well distributed indirect lighting effect (reilection from the ceiling) is obtained.

a combination of direct and indirect lighting is f obtained. 'I'he lamps 26d, positioned about as in Fig. l, deliver light upwardly between the casing members 'l0 and Il, and downwardly through windows 2l in the lower casing member Il.

In the form shown in Fig. 4, a lamp 26 is positioned centrally below the upwardly concaved ,bottom 28 of the lower casing member IlA the inlet grille I2a in this case being higher up as shown. The lower face of the bottom 28 serves as a reiiector. AA lamp shade 29 may also be usedl to diiuse the direct downward rays of the lamp. The xture may be supported in any suitable manner, as by means of the spider 30 having arms the ends of whichare attached to brackets 3| and 3Ia secured at ytheir -lower ends to the eave I4. The fan motor 32 is hung from the hub of the spider 30. Resilient suspensions 33 connect the spider to the ceiling 34a.'

The bracket 3| a serves as a header to. convey i' uuid from one of the tubes a4 te the element 25 and back to the other tube 34, the latter being connected to a remote source of refrigeration Y. .in which a dished housing is preferably adapted' or heat.

It will be noted that I have provided a fixture both for distributing conditioned air radially just beneath a ceiling, and reflecting light rays from lamps carried by it, .upwardly and radially outwardlyagainst the ceiling so as to obtain a, most eicient and complete indirect'lighting effect.

It will be understood that the invention may be embodied either in a ceiling hung unit,v as illustrated in Figs. 1-4 inclusive, or in a pedestal type unit as shownin Fig. 5 wherein the mechanism is supported on a pedestal 40 terminating at its upper end' in arms 4| carrying the support to the bottom of the casing Il.

Another form ofthe invention is embodied in the wall hung unit shown in Fig. 6, wherein a wall bracket 42 vhas the arm 43 supporting the casing Il from below, and an arm 30a carrying Athe motor fan ntempering element assembly irom above. y
